Borno govt, MSF vaccinates 350,000 children against diphtheria in Maiduguri

The humanitarian medical organisation Médecins Sans Frontières (MSF) and the Borno State Government have completed a vaccination campaign against diphtheria targeting children up to 14 years old in the Maiduguri Metropolitan Council in the state.

This was contained in a statement by Abdulkareem Yakubu, Field Communication Officer, Médecins Sans Frontières, to Journalists in Maiduguri on Thursday.

The statement noted that the campaign began with a first round from 9 to 15 February 2026, which reached 490,000 children, far exceeding the initial target of 387,000.

A second round was conducted from 9 to 15 April 2026, targeting 360,000 children reached during the first round to strengthen immunity. Despite the high number of children reached, limited vaccine availability constrained the scale of response.

“This vaccination will help to significantly boost the immunity levels of children below 14 years old in Maiduguri, the area responsible for most of the diphtheria cases we saw in our treatment centre. This proactive step is essential to controlling and preventing the disease,” said MSF emergency coordinator for the project, Nao Muramoto.

In addition, MSF supported the diphtheria treatment unit (DTU) at Maiduguri Teaching and Training Hospital in collaboration with the Ministry of Health.

The DTU saw a surge in suspected cases during the campaign, reflecting heightened awareness and improved referrals by community health workers during the vaccination efforts.

“Sustained routine immunisation against diphtheria, improved access in volatile areas and tackling vaccine hesitancy remain essential to prevent future surges of vaccine-preventable diseases like diphtheria. Access to more vaccines is needed, as efforts to reach the children of Borno State should remain a priority to avoid further contaminations, to cut the transmissions and save lives,“ concludes Nao Muramoto.

Nigeria is grappling with one of its most severe diphtheria epidemics in history, with the National Centre for Disease Control (NCDC) reporting 65,759 suspected cases and 2,229 deaths as of 22 March 2026, since May 2022 and officially declaring an outbreak in 2023.

In Borno State, one of the most affected areas, MSF has treated more than 7,400 suspected cases since 2023, including 4,200 in the past year alone.

Furthermore, MSF is treating thousands of people suspected or confirmed to have diphtheria across the country, in close collaboration with state Ministries of Health, and currently supports activities in Bauchi, Borno, Kano and Sokoto states.

“Diphtheria is an acute infectious disease that spreads primarily through respiratory droplets or contact with infected wounds. Symptoms include a sore throat, fever, swollen lymph nodes and a thick grey membrane in the throat that can obstruct breathing.

In severe cases, the bacterial toxin can damage the heart, nerves and kidneys, potentially leading to complications such as paralysis. For unvaccinated persons without proper treatment, diphtheria can be fatal in around 30% of cases, with young children at higher risk of dying.”MSF said.

MSF supported the Borno State Ministry of Health to run the vaccination campaign, providing comprehensive logistical support including vaccine storage, transportation and remuneration for vaccination teams, health promotion and awareness activities, and program supervision. Hallelujah

The Ministry of Health provided the vaccines used in the campaign. This collaborative effort ensured high coverage, with communities responding enthusiastically to outreach efforts across both rounds.
